Damsels are notorioius for being agressive. Not much will fit with a damsel unless you have a large enough tank so they arent always seeing eachother.

just a word of caution about box fish...... when they die/stressed, they are notorious for secreting their slime coat which can/will wipe out your tank. Someone I know had a small 3" box fish and when it died, it took everything in his 200g tank with it (all inverts survived)

I would recommend getting rid of the damsel if you want your box fish to survive

I thought box fish - because they're not very fast or aggressive...need a species only tank...or with very easy-going tankmates...

just to end this post i've taken the damsel back to the shop. the guy at the shop said it was ok to bring him back. thank god thanks for the advice.
